Fig. 1.

Structural, optical and temporal properties of as synthesized, functionalized with PEG-monooleate and protonated NCs (first, second and third column, respectively). Top row presents TEM pictures. Second row schematically depicts ligand to the NCs’ surface binding for (i) oleic acid, (ii) PEG-monooleate and (iii) hydroxyl group. In the third, fourth and fifth row, photoluminescence spectra, PL decay times and decay time distribution calculated with the Maximum Entropy Method (MEM) are presented, respectively. The emission spectra were recorded upon λ _exc = 395 nm excitation
